After her defeat at the French Open, Nastya gave an interview that helps to explain her situation.
She had surgery on her left foot in January and it seems playing on it made it swell up again. She says she still loves tennis but she says that she wouldn't be happy just being a top 80 player, so would have to be able to compete at top 10/top 5 level in order to continue so...whilst she was away she was comentating and doing sports TV shows (like compatriot Krasnoroutskaya).
